Abstract
(EN)
Implantable aneurysm-sac treatment devices include an implantable coil body configured and sized to reside in a sac of an aneurysm. The body has an inductance and capacitance. The capacitance is selected so that the coil resonates at a Larmor frequency of a predefined magnetic field strength.
(FR)
L'invention concerne des dispositifs implantables de traitement de poche anévrismale comprenant un corps de bobine implantable qui est configuré et dimensionné pour loger dans une poche anévrismale. Ledit corps présente une inductance et une capacité. La capacité est sélectionnée de manière que la bobine résonne à une fréquence de Larmor à une intensité de champ magnétique prédéfinie.
